Waterproof construction method for anti-floating anchor rods

Abstract

The invention discloses a waterproof construction method for anti-floating anchor rods. The waterproof construction method for anti-floating anchor rods includes the following construction steps that A, a concrete cushion is poured; B, cement paste is poured around the anti-floating anchor rods; C, cement-based crystallization waterproof paint is brushed; D, a waterproof roll layer is laid; E, waterproof grease is poured, and a waterproof protection layer is poured. The waterproof construction method for anti-floating anchor rods has the advantages that gaps between the anchor rods and bed rock can be effectively sealed for avoiding water burst; the problem that because waterproof paint on the root portions of rebars of the anchor rods is not compact, water is prone to leakage is solved; a water stop steel plate can stop capillary water from rising along rod bodies to cause water seepage hazards, the water stop effect is good, and leakage resistance is improved.

Description

technical field [0001] The invention relates to a waterproof construction method for building construction, in particular to a waterproof construction method for anti-floating anchor rods. Background technique [0002] At present, in the underground structure of construction projects, the anti-floating anchor directly connects the bedrock and the bottom plate, and penetrates the waterproof layer of the base, so the possibility of water seepage increases greatly. At present, there is no anti-floating anchor node waterproof treatment in the current atlas waterproofing method, and the anti-floating anchor waterproof node treatment generally adopts the pile foundation waterproofing method of building waterproof structure; but the diameter of the pile foundation is usually larger than the anti-floating anchor diameter, compared to the pile foundation The horizontal operating surface is much smaller, and it is difficult to guarantee the waterproof effect when painting cement-based...

AI Technical Summary

Problems solved by technology

At present, there is no anti-floating anchor node waterproof treatment in the current atlas waterproofing method, and the anti-floating anchor waterproof node treatment generally adopts the pile foundation waterproofing method of building waterproof structure; but the diameter of the pile foundation is usually larger than the anti-floating anchor diameter, compared to the pile foundation The horizontal operating surface is much smaller, and it is difficult to guarantee the waterproof effect when painting cement-based permeable crystalline waterproof coatings; the top surface of the pile foundation is usually 50mm higher than the base layer of the waterproof layer, and the anti-floating anchor is level with the bearing layer of the foundation when grouting. That is, the top surface of the anti-floating anchor is lower than the base layer of the waterproof layer, which cannot close the waterproof layer

In addition, if the anti-floating anchor rod is at the water gushing point of the bedrock, the water gushing point cannot be blocked simply by sealing with sealing ointment, and the capillary water path rising along the rod body is long, leaving hidden dangers of water seepage
